[Bug 2000015] Re: autopkgtest unshare-qemuwrapper doesn't build chroot with sbuild from lunar-proposed

[Mauricio Faria de Oliveira]

For documentation purposes, the autopkgtests pattern observed
on packages w/ the sbuild versions in lunar-release/proposed:

With sbuild 0.83.1ubuntu1:
(dpkg, courier, postfix, sendmail, bcron, mmdebstrap, python-psutil, [gnupg2, perl])

autopkgtest [HH:MM:SS]: @@@@@@@@@@@@@@@@@@@@ summary
build-procenv        PASS
unshare-qemuwrapper  SKIP installation fails and skip-not-installable set
unshare              FAIL non-zero exit status 1

With sbuild 0.84.1ubuntu2:
(sbuild, qemu)

autopkgtest [HH:MM:SS]: @@@@@@@@@@@@@@@@@@@@ summary
build-procenv        PASS
unshare-qemuwrapper  FAIL non-zero exit status 1
unshare              PASS

With sbuild 0.84.1ubuntu3:
(hopefully all PASS.)

Title:
  autopkgtest unshare-qemuwrapper doesn't build chroot with sbuild from
  lunar-proposed

Status in sbuild package in Ubuntu:
  In Progress

Bug description:
  The autopkgtest `d/t/unshare` uses `sbuild`, which fails on lunar
  (sbuild 0.83.1ubuntu1) as the chroot setup cannot find `adduser`
  (not in the chroot as it's now an alternative dependency in `apt`).

  This is fixed in lunar-proposed (sbuild 0.84.1ubuntu2; commit [1])
  since it no longer depends on `adduser` in the chroot.

  [1]
  https://salsa.debian.org/debian/sbuild/-/commit/0d35fa019a5c6d51e0928987a87849766b0f35e6

  However, `d/t/unshare-qemuwrapper` runs `d/t/unshare` in a qemu vm,
  but its image still does _not_ ship `sbuild` from lunar-proposed,
  thus `unshare` fails anyway (and its parent `unshare-qemuwrapper`).

  The reason is, even though the apt _sources_ are used to build the
  vm disk image thus `lunar-proposed` is _available_, it is not used
  because apt _preferences_ (`autopkgtest --apt-pocket=proposed=src:...`)
  are not copied in.

  This is now required as lunar has -proposed pocket w/ NotAutomatic.

  Just checking for/copying the apt preferences file/dir address it:
  + mmdebstrap ... --setup-hook=sync-in /etc/apt/preferences.d/ ...

  Tests:
  =====

  $ autopkgtest-buildvm-ubuntu-cloud -a amd64 -r lunar

  Before:

  $ autopkgtest sbuild \
